Abstract: A game system and method utilizing quantum phenomena, such as entanglement, superposition and interference, to modify game play of a conventional game. The game of chess is one such game. As detailed herein, the manner in which quantum phenomena are integrated into the chess game allows players to strategize based on at least entanglement, superposition, measurement and interference. That is, the integration of quantum phenomena is not simply overlaid on the chess game but rather integral to how the chess game is played. The embodiments of the present invention are also predicated on game measurements being non-deterministic.
